BX22 fuel filters

[bellweather]

After I bought a new fuel filter and installed it under the tractor (it's located up stream of the fuel pump), I realized that there is a 2nd fuel filter in the engine compartment. Do most folks replace both, or just one or the other?

BTW, if you haven't done this before, I recommend having stoppers handy to plug the open fuel lines.

I've replaced the rear one twice, and the front one once. My tractor has about 250 hours on it, and I have had a gelling issue or dirty fuel issue the last two winters. I really think it was just the rear filter, but the last time I just replaced them both.

I just try and make sure I have the new filter ready and plug the end of the line with my finger, but I usually end up with fuel running down my arm any way.

Since the filters are identicle I would expect the one under the tractor to get plugged more often. It will also be the one one to "gel" quicker since it is on the "inlet" side of the pump and does not get any radiant heat from the engine either.

I just replaced both of mine so I would have a base line for future changes.

I put a valve in mine at the first change.

I think it is a bit ridiculous that there are two fuel filters. I am trying to find one consiter type fuel filter that I can replace both of them with just one in the engine compartment.

As for which one to replace, I would opt for the first one in the series as this is going to be the one to clog first. BTW, vice grips work pretty good at clamping the lines off to limit the amount of fuel that leaks out.

If you do it that way you will lose protection for the primary pump, or are going pipe it back to the pump???

Having 2 identical filters doesn't really make the protection any better. If contanimants get past one filter is most likely going to get past the second filter.

Other tractors use just one filter. Even the new Kubota's have just one filter.

I believe the question was: are you going to put this filter before or after the fuel pump?

That is correct. His wording sounds like it will only protect the injection pump. Also the rubber hose could deteriorate after the filter prior to the injection pump.

All my other Kubotas have just one proper filter near the injection pump but I do not belive they have the transfer pump.

At about 250 hours, my BX23 started loosing power under load. I found the rear filter plugged with muck. At the time, I only replaced the rear filter. Soon I will reach the 400-hour mark and plan on replacing both filters.

I can稚 imagine running without this first filter, as it is protecting the in-line pump which probably costs as much as 20 filters, and would certainly have failed if the gunk I found in the first filter, had passed through it.

Kubota didn稚 put two filters in the system just so they could sell twice as many filters. In this case, more is better.
